Abstract

La présente invention concerne un câble de détection d'incendie sensible à la température du type à ligne analogique, y compris deux conducteurs de détection disposés en parallèle. Une couche obstructive caractéristique CTN et une couche d'isolation fusible sont insérées entre les deux conducteurs de détection disposés en parallèle, avec la particularité qu'une couche conductrice intermittente est insérée entre la couche obstructive caractéristique CTN et la couche d'isolation fusible dans la direction longitudinale du câble de détection incendie, au moins un des deux conducteurs de détection étant un conducteur élastique. L'invention pallie les défauts associés aux températures d'alarme imprécises causées par la conductivité insuffisante des deux conducteurs de détection lorsque le détecteur de température de type à ligne analogique, selon l'état antérieur de la technique, est chauffé.
